' SPECIFIATION forming part of Letters Patent N0. 761,899, dated June 7, 1904.

Application filed September 15, 1903. Serial No. 173,349. (No model.)

To all whom it may concern/f Be it known that I, LESTER NEVERS, a citi- Zen of the United States, residing at Grand ,Rapids, in the county of Kent and State of Michigan, have invented certain-new and useful Improvements in Split Pulleys; and I do `hereby declare thefollowing to be a-full, clear,

vide a strong and cheap structure, to provide improved means for securing a wood rim to metallic arms, and lto provide the same with `certain new and useful features hereinafter more fully described, and particularly pointed ...2O t

out in the claims.

My device consists, essentially, of a divided rim made of segments; arms connected to each part of the rim, said arms being arranged in pairs and connected at their inner ends by short segments to engage thel shaft and at their outer ends by longer segments interposed between the segments of the rim and secured by bolts or rivets; spacing-blocks between the inner segments, and clamps consisting of bars engaging the arms and connected by bolts passing-between the arms and at each side of the shaft, whereby the inner segments are clamped upon the shaft, as will more fully appear by reference to the accompanying drawings, in which- Figure l is a side elevation of a pulley em pair of arms and their segments,'and Fig. 5 a

detail of one of the spacing-blocks.

A represents the rim, divided at opposite.

sides and in the plane of the aXis. This rim is preferably made up of the larger segments A' between the segments D" of the arms andspacing the same apart and the smaller fillingsegments A" to complete the rim in the plane .of the vsegments D".

The arms or spokes consist of integral arches D, extending from points about ninety degrees apart in the rim and equidistant from the division thereof and with vthe middle portion provided with segments D to fit the outer surface of the bushing C or the largest shaft that the pulley is intended for, and at the outer ends these arches are connected by outwardly curved segments D, adapted to be interposed between the segments A', and thus form a part ofthe rim, and are secured to the same by suitable bolts or rivets I. These arches and segments' are made integral and preferably of the same thickness throughout, and thus they may be conveniently stamped or cut from sheet metal. To further secure these segments DIl to the rim, theyare provided at each end with outof the rim. Each arch and the segments therewith thus constitute an integral and continuous frame, as shown in Fig. 4, thus forming a strong and rigid structure to connect the rim and shaft, Between the lsegments Dl are placed segmental filling-blocks H of the same thickness as the segments A', whereby a continuous concav'enhub portion' is provided to engage the shaft B or bushing C, and the series aresecured by a suitable bolt or rivet E.

To secure thepulley upon the shaft, clampbars G are provided to engage the arches D close to the ends of the segments D', and bolts F are inserted in openings in the said bars and 'extend at each side of'the shaft and between the arches,and thus clamp the segments D' and filling-blocks H firmly against the oppo- Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a pulley, integral members to connect the shaft and rim, comprising two oppositelycurved segments joined to each other at the ends, one of said segments adapted to be attached to the rim and the other segment having an oppositely-curved integral middle portion, adapted to engage the shaft.

2. In apulley, arches having segmental middle portions to engage a shaft, integral segments connecting the ends of the arches, a rim having segments interposed between the segments of the arches and attached thereto, and lilling-blocks between the middle portions of the arches.

3. In a pulley, arches having middle portions adapted to engage a shaft, integral segments connecting the ends of the arches, a rim having segments between the segments of the arches and attached thereto, filling-segments in the rim and in the plane of the arches, and filling-blocks between the middle portions of the arches.

4t. In a pulley, the combination of a rim divided in the plane of its axis, arches having middle portions adapted to engage a shaft, integral segments connecting the ends of the arches and attached to the rim, filling-blocks between the middle portions of the arches and clamps consisting of bars engaging the arches and bolts extending through openings in the bars and between the arches.

5. In a pulley, the combination of arches posed between the segments of the arches and v attached thereto, and lilling-segments in the plane of the arches and engaging the spurs on the ends of the segments ol the arches.

6. A split pulley comprising a wood rim divided in the plane otl its axis, metallic arches A arranged in parallel planes and having segmental middle portions to engage a shaft and integral segments connecting their ends and secured to the rim, lilling-blochs between said arches and clamps consisting ot' bars engaging the arches and bolts extending through the bars and between the arches.

7. A split pulley consisting ol metallic arches spaced apart in parallel planes and having segmental middle portions to engage a. shaft and integral segments connecting their ends, a rim divided in the plane of its axis and having segments between the segments o l the arches and secured thereto, and also having iilling-segments in the plane of the segments of the arches, and a clamp consisting ol' bars engaging the arches and bolts extending through the bars and between the arches.

In testimony whereof I aix my signature in presence ot' two witnesses.
